Horizon Client computer
or client access device
You must have one of the following installed to avoid video playback issues:
n
GStreamer core library and gstreamer-ffmpeg 0.10
n
GStreamer core library and fluendo 0.10
On SLED 11 SP4, if you encounter video playback issues such as a black
screen, remove the library libvdpau.
On HP thin clients, you must remove the
file /usr/lib/gstreamer-0.10/libgstfluvadec.so to avoid video playback
issues such as a Horizon Client crash or a black screen.
On Dell Wyse thin clients, video playback might not work with the pre-
installed fluendo library. To resolve the problem, contact Dell support to
obtain the latest fluendo library.

Requirements for Using Flash URL Redirection
Streaming Flash content directly from Adobe Media Server to client endpoints lowers the load on the
datacenter ESXi host, removes the extra routing through the datacenter, and reduces the bandwidth
required to simultaneously stream live video events to multiple client endpoints.
The Flash URL redirection feature uses a JavaScript that is embedded inside a Web page by the Web page
administrator. Whenever a virtual desktop user clicks on the designated URL link from within a Web page,
the JavaScript intercepts and redirects the ShockWave File (SWF) from the virtual desktop session to the
client endpoint. The endpoint then opens a local VMware Flash Projector outside of the virtual desktop
session and plays the media stream locally. Both multicast and unicast are supported.
This feature is available when used in conjunction with the correct version of the agent software. For View
5.3, this feature is included in the Remote Experience Agent, which is part of the View Feature Pack. For
View 6.0 and later releases, this feature is included in View Agent or Horizon Agent.
To use this feature, you must set up your Web page and your client devices. Client systems must meet
certain software requirements:
n
This feature is supported for PCoIP only. This feature is not supported on ARM processors.
n
Client systems must have IP connectivity to the Adobe Web server that hosts the ShockWave File (SWF)
that initiates the multicast or unicast streaming. If needed, configure your firewall to open the
appropriate ports to allow client devices to access this server.
n
Client systems must have the appropriate Flash plug-in installed.
a Install the libexpat.so.1 file, or verify that this file is already installed.
Ensure that the file is installed in the /usr/lib or /usr/local/lib directory.
